LCD photo-lithographic 3D printers
These machines were my bachelor thesis project. They were made to bring cheap alternative for rapid prototyping. A classical LCD display is use to mask UV led matrix beam. A photosensitive liquid resin is stocked in and injected in printing bath with a pump. All design was thank to be user friendly and hardly repairable. The PETITE and GRANDE models can be found here, choice is yours.
These are not ready to business, but soon maybe.
